able others skilled in the art to which it ap-v pertains to make and usethe same. This invention relates to improvements in ball flush valves,andhas for one of its objccts the provision of a device of this char- 1acter which can be'readily reversed upon the valve stem when one portionthereof has become worn.

Another object, of 'this invention isthe provision of aper'forated tubehaving means at each end for securing it in the ball and either of saidmeans adapted to have the valve stem secured thereto, While the unusedmeans will permit air to enter the tube and thence into the ball.

A further object of this invention is the provision of a ballfiushva'lve of the above stated character, which will be simple, durableand ellicient, and which may be manufactured and sold at a comparativelylow cost.

l Vith these and other objects in view, as will become more apparent asthe description proceeds, the invention consists in certain novelfeatures of construction, combination and arrangement of parts as Willbe hereinafter more fully described and claimed.

For a complete understanding of my invention, reference will be had tothe following description and accompanying drawing, in which:

Fig. 3 is an enlarged fragmentary vertical sectional view, illustratingthe modified manner of securing the tube in the collars.

Referring in detail to the drawing, the numeral 1 indicates as anentirety a ball flush valve consisting of a spherical body 2 of hollowformation, preferably constructed Patented Dec. 3, 1918.
